Abstract

A microswitch in which a good snap action feeling is obtained and an operating stroke is large is provided. Included in the microswitch is a swingable lever (23) which is pushed by a pressing projection (21d) of a push button (21) swingably pivotally supported. One end of the lever (23) is pivotally supported and the other end is coupled with one end of a movable member (18) having a movable contact (19). The movable member (18) is biased by a spring (26) in one direction.
